/* ---------- 有偿资讯卡片 ----------
   版式刻意 1:1 复刻小程序信息流的 `.pcard`（pages/feeds/index.wxml + wxss），
   目的是让审核方一眼看出「网站和小程序是同一个平台」。
   小程序用 rpx（750 设计稿），此处按桌面端比例换算成 px，但**保持原有的相对关系与裁切比例**：

     pcard        padding 24rpx            → 20px
     ptag         24rpx / 圆角 6rpx        → 12px / 4px
     ptime        24rpx #B9BEC5            → 12px
     pcard-cover  210×180rpx（7:6 裁切）  → 190×163px（同为 7:6，装 3:2 素材只裁约 12%）
     pcard-title  30rpx / 500 / 行高 1.4   → 17px
     pcard-desc   24rpx / #8A8A8A / 行高 1.5 → 13.5px
     pcard-av     30rpx 圆形               → 16px 圆形
     pcard-name   24rpx #5A6270            → 12.5px
     pcard-loc    24rpx #9AA0A6            → 12.5px

   ⚠️ 不要再往这里加"网站独有"的装饰样式 —— 一旦和小程序长得不一样，
      "同一平台"的直观印象就没了，这条改动的意义也就没了。 */
